Crap! Just what we need. Another dormant supervolcano similar to Yellowstone getting active again.
There are two known magma chambers in the Long Valley complex: one under the existing Long Valley caldera and one under the Mono-Inyo volcanic complex. Both are far enough away from the Hawthorne swarm to make it unlikely that they are directly involved. Of course, there COULD be a previously unknown magma source involved...
